Bentley Navigator is a desktop application that enables you to visualize, navigate, and interact with intelligent 3D models of large, complex facilities using both graphical and non-graphical facility information. With Bentley Navigator, you can quickly and easily review equipment layouts, assess maintenance access and make informed design decisions. Bentley Navigator lets you perform detailed interference analyses and interference reviews before assets are under construction, as well as interact and walk through intelligent DGN and DWG models. You can also simulate construction activity and movement of materials within the facility.
